o i was riding along and all of a sudden it felt like i was deaccelerating in like 2 second intervals almost like it had fuel, then no fuel. then i down shifted to get it into a gear to up the rpms... wel as soon as i took it out of gear and the rpms dropped it died! waited a minute and it started again so i started heading for home sure enough same thing happened 1 mile later. so i pull over look at the fuel lines... there is fuel... but then i saw something float in the fuel line in the hose right below where you change it from "Reserve to ON" ect it went up into the place where you choose where the fuel comes from? so finally it started again but as soon as i pulled int my neighberhood same thing!

this is terrible i just got the stupid thing:(

could this be something coming from out of the tank? or maybe something else please help me!

check the tank for rust. my old ex500 had a rusty tank, so i had to replace the petcock(the part where u switch to on/off/reserve) assembly and fuel filter cuz it got clogged up.

edit, the parts i mentioned replacing were cheap

sound like the engine is being starved for fuel. I'm thinking you have something in your lines or your tank is not breathing right!

well i cant do the fuel tank opening thing i only have 1 key atm. the guy i jsut bought from said when i bought it there was no rust in it atm and as a matter of fact it had a coating of that anti rust whatever it is. i truely believe the guy to be honest so... the bike was jsut apart due to the fact he just painted it... could it have been an air bubble rather then an object? and what could that mean? ill go check to see if i see any hoses crimped

well just run your bike for a little, let it warm up and just rev it a little, take the key out and open the cap, see if it has suction

the air vent hose on my r6 was jacked up and it wasnt being ventilated, it made it die and i couldnt figure it out, but i opened the cap and i heard it suck in a bunch of air

I had a similar problem with an fzr I had, it would run fine then cut out and when I would pull the clutch in to down shift it would die.The problem ended up not being a gas problem or lack there of, it turned out to be the "brain" on the bike.Once the bike warmed up it would cut off. I would suggest cranking up the bike letting it run untill it cuts off , then pull a plug wire to make sure it's still getting spark.it may not be he problem but it's worth checking out..

After you filled the bike with 3.2 gallons of gas, did the bike run normal or not?
